I just purchased a 96vet out of Denver,Co. and brought it to the Nevada desert. After a week of driving I've noticed the engine temp is getting hotter, almost to the danger zone once. My reaction is to have the radiator flushed and replace the thermostat. Help if you please...it's my first corvette and " I LOVE DRIVING ALL OVER AGAIN" Thank You. P.S. To be specific it's my water temp gauge that's showing high heat.
